Patented Nov. 28,1905,

Application filed March 20, 1905. Serial No. 251.107.

To all whom it may concern:

Be it known that 1, CHARLES A. PETERSON, a citizen of the United States, residing at Franklin, in the parish of St. Mary and State of Louisiana, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to improvements in oil-burners of that type particularly designed for use in furnaces or in similar capacity and burning crude oil.

rl`he essential feature of the invention resides in the general simplicity of the burner and in the special construction thereof whereby the thorough vaporization of the fuel is facilitated to increase to a maximum the intensity of the flame and promote combustion to the greatest extent possible.

For a full description of the invention and the merits thereof and also to acquire a knowledge o f the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which v Figure 1 is a view, partially in section, showing clearly the operative parts and connections comprising the burner. Fig. 2 is a transverse sectional view taken on the line X X of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in both views of the drawings by the same reference characters.

The burner comprising this invention is of the class embodying a suitable inlet-chamber to which the fuel is supplied for the chamber',

' a mixing-chamber in which the steam and oil are commingled, and a vaporizing-chamber from which the fuel is burned.

The numeral 1 designates a T-coupling the interior of which constitutes an inlet-cham ber 2. The coupling 1 is connected at one end with an injector-nozzle 3, threaded thereto and tapered toward its innermost extremity. The nozzle 3 connects with a steam-supply pipe 4, which is provided with a suitable valve 5. The mixing-chamber is indicated at 6 and consists of a tubular body or tube. The tube 6 is threaded into a plug' 7, which latter is externally threaded and screwed into the end of the coupling-1 opposite that -in which the nozzle 3 is carried. The mixing chamber or tube is surrounded or inclosed by a vaporizing-chamber 8, likewise consisting of a tubular body having suitable threaded connection with the end of the coupling 1, in which the tube 6 is screwed. The lower end of the chamber or tubular body 8 is provided with a suitable jettip 9, which may be applied thereto by threaded joint or in any similar way. The oil-supply pipe 10 is connected with the T-coupling 1 between the ends of the latter, and this pipe 10 is also provided with a valve 11, the valves 11 and 5 being utilized to govern the supply of steam and oil in a manner which will be obvious.

rlhe construction of the mixing-chamber is of special importance in the contemplation of this invention, said cham ber being divided into a plurality of compartments by means of a longitudinal centrally -located partition 12. The partition 12 extends from one end of the chamber 6 to the opposite end, dividing said chamber into two compartments, in this instance perforations or apertures 13 being provided in the tubular body of the mixing-chainber, extending at diametrically opposite sides thereof for each of the compartments. rlhe form of the nozzle, which is tapered, as above mentioned, lconduces to the thorough commingling of the steam with the oil and the atomization of the latter, in that the steam is adapted to enter the inlet-chamber 2 with great force, drawing the oil in therewith and separating the latter in a manner conducive to the most thorough atomization thereof. The mixing of the steam and oil and the thorough vaporization thereof is greatly promoted by the structure of the mixing-chamber 6, since the compartments into which said chamber is separated are each closed at one end at opposite extremities. The compartments of the mixingchamber are designated aand 6b, and the closed end of the compartment 6is remote from the injector-nozzle 3, as shown at 12, the closed end of the compartment 6l being' adjacent said injector-nozzle, as shown at 12b. The plug 7, into which the tubular body of the mixingchamber is screwed, has an opening entirely therethrough, the end of the openi-ng adjacent the nozzle 3 being iiared, so as to concentrate and deflect the steam and oil into the mixingchamber, the iiared portion above mentioned being shown at 14. The extremity of the mixing-chamber remote from the nozzle 3 is surrounded by a ring 15, which forms a closure between this end of the mixing-chamber and the vaporizing-chamber 8, so that as the steam and oil passes into the compartment 6 from the inlet-chamber 2 the fuel is caused to pass through openings or apertures 13 of this compartment out into the space between the mixing-chamber 6 and the chamber 8, thence back IOO into the compartment 6b of the mixing-chamber, and out of the mixing-chamber at the open end of said compartment 6b. The comming-led steam and oil passes into the mixing-chamber compartment 6u through the apertures 13 of this compartment, and it will be noted that the circuitous course which must be taken by the elements of the fuel is of importance in securing the fullest commingling or mixture thereof to promote the production of the greatest amount of combustion'practicable, the intensity of the iilame of the burner being dependent upon this feature.

Having thus described the invention, what is claimed as new is- 1. In an oil-burner, the combination of a mixing-chamber divided into a plurality of compartments, a vaporizing chamber surrounding the mixing-chamber, the mixing- -chamber being provided with apertures for the compartments thereof, and means for forcing fuel into an end of one compartment of the mixing-chamber whereby the fuel is conducted through said apertures and vaporizingchamber to a second compartment and discharged.

2. In an oil-burner, the combination of a mixing-chamber composed of a tubular body divided into a plurality of compartments, an opposite end of each compartment being closed, apertures in the body of the mixingchamber for each compartment thereof, a vaporizing -chamber surrounding the mixingchamber, and means for supplying steam and oil to one end of one compartment of the mixing-chamber.

3. In an oil-burner, the combination of a mixing-chamber comprising a tubular body, a partition longitudinally of said body dividing the same into a plurality of compartments, a vaporizing-chamber surrounding the mixing-chamber, an opposite end of each compartment of the mixing-chamber being closed, apertures establishing communication between each compartment of the mixing-chamber and the space between said mixing-chamber and the vaporiZing-chamber, means for supplying steam and oil to one end of the mixing-chamber, and means at the' opposite end of the mixing-chamber for closing the space between this chamber and the vaporiZing-chamber.

4. In an oil-burner, the combination of the mixing-chamber comprising the tubular body 6, the inlet-chamber 2 for said mixing-chamber, the compartments 6 and 6b of the mixing-chamber having outlet-apertures, the closures l2 and 12b for said compartments, and the vaporiZing-chamber comprising a tubular body surrounding the mixing-chamber.

In testimony whereof I afiix my signature in presence of two witnesses.
